Now, nearly two years later, the project he’d been working on is coming to theatres across the country; called Sharkwater Extinction, Stewart and his team once again take a close look at the illegal harvesting of shark fins and sharks as a whole for food, medicine and numerous other uses. Along the way, the shark advocate makes some very powerful enemies.

Sharkwater Extinction illustrates how rampant shark finning still is. Shark fin soup is still being consumed on an enormous scale, and endangered sharks are also being used to make products for human consumption. Stewart’s lifelong mission was to save the sharks and oceans before it’s too late.
